AFP: New skull and crossbones signs warn of mines in Ukraine

Explosive devices killed 21 people and injured 57 in the preceding three months in eastern Ukraine

"Danger! Mines! Do not leave the road!", warns a billboard painted with an ominous skull and crossbones on a blood-red background that stands on a roadside in war-torn eastern Ukraine.

Though fighting between Kyiv's forces and pro-Russian rebels has dwindled after nearly two years, mines scattered across the vital industrial region that is home to some three million people continue claiming lives at an alarming rate.
